My Outback Sport / manual gear box is making a clicking noise when
driving. It seems to only make the noise under load but not when I
rev the engine in neutral. Almost sounds like lifters tapping, but it
is not.... Could it be coming from the clutch / tranny???

Engine has 55,000 miles on it.

Wow, could be so many things. maybe if you describe the sound better.
One thing I would suggest you check are the CV joint boots. Also, double
check your lug nuts.

i dunno

It is a clicking noise, sounds like lifters tapping or an exhaust
tick.. If I leave off of the gas, the noise is gone. There is really
no other way of describing it...

I'm gonna say more likely heat shields than anything else. Does the
sound change frequency with RPM. (That is, is the ticking slower at
-say- 35mph in 4th gear than in 3rd gear?) Does it sound the same when
you lift off the throttle but are still coasting?

I do not hear much of a change in frequency. Not real loud in the
car, but when I pass someone I can hear it pretty good. When you are
shifting, it goes away. If I lift off of the gas, it either goes away
or it is not as loud. I was thinking it might be something in the
trans/clutch.

Maybe the belt tensioner? I have an '03 Impreza Wagon that was making funny
ticking noises (especially when cold) and this turned out to be the problem.
Here is a bit more info:
